About Toyota Headlight Switch
A Toyota headlight switch is responsible for controlling the parking lights, driving lights, and the headlights. Headlights rarely fail, but there are some instances when they don't activate because of a damaged Toyota headlight switch. Just like any other switch in your car, Toyota headlight switches open and close electrical circuits. But if what you've got is a busted Toyota headlight switch, then the only solution to this issue is by replacing your old part with a new one.
